feat(phase3): write snapshot objects to S3 at all 3 write sites (issue #63)

All snapshot write paths now call backend.put(snapshot_id, snapshot_to_bytes(...)) and populate MusehubSnapshot.storage_uri: - upsert_snapshot_entries (primary path — called by merge_proposal, commit_files_to_repo, push receive) - repair_snapshot_on_push (repair path in wire_push) - wire_push bulk insert (new snapshots from push receive)

Adds snapshot_to_bytes() helper to musehub/muse_cli/snapshot.py producing canonical muse binary format: snapshot <size>\0<json>. manifest_blob (msgpack) retained as DB cache for intel/GC hot paths.

14/14 phase 1 tests GREEN. 133 existing tests unaffected.
